From the TV 5 Forecast Center:
Low pressure located off the Mid-Atlantic coastline this morning is forecast to travel northward along the east coast into the Gulf of Maine by Friday morning then into the Bay of Fundy later Friday. With the track of this storm being so close to the coastline, we’ll see varying types of precipitation across the state as milder air moves into the mid and low levels of the atmosphere. Precipitation is expected to fall as mostly snow with maybe a little sleet mixing in along and north of a line from Houlton to Millinocket to Rangeley. Snow will likely change to a mix of sleet and freezing rain over much of the rest of the state with the exception of the Midcoast through coastal Downeast areas where we will likely see a changeover to all rain during the night tonight. The changeover to all rain will keep snowfall accumulations to a minimum for the Midcoast and coastal Downeast locales.
As of noon time today, snow has spread into the greater Bangor area points south and west and will continue to spread northward across the rest of the state this afternoon and evening. Temperatures should be warm enough along the coast so that snow will mix with some sleet later this afternoon and evening while precipitation remains all snow elsewhere. Precipitation will continue to spread northward and pick up in intensity, falling heavily at times during the night tonight. Warmer air moving into the mid and low levels of the atmosphere will cause the snow and mix to change to all rain along the coast and snow changing to sleet and freezing rain over inland locations with as much as .25” of ice accumulation possible. Snow is expected to fall with possibly a little sleet mixing in for areas along and north of a line from Houlton to Millinocket to Rangeley. Precipitation will taper off from west to east across the state Friday morning. Any mix and/or rain will likely change back to a brief period of snow before ending. By midday Friday, accumulations will range from 4”-8” (most of which will accumulate later today and early tonight before the changeover to rain) over coastal Hancock and Washington County; 4”-8” for central Washington County, interior Hancock County and the Midcoast; 8”-12” for northern Washington County, southern Penobscot County, over towards Skowhegan and Farmington then down through Augusta and Waterville points south; 12”-18” along and north of a line from Vanceboro to Dover-Foxcroft to just north of Rumford.
Upper level energy moving through the Great Lakes region and Ohio Valley will cause a new storm to develop off the Mid-Atlantic coast Friday night. This new storm will then travel northward towards eastern Nova Scotia bringing us some snow showers Saturday afternoon. If the storm tracks closer to New England then we could see some steadier snowfall later Saturday and Saturday night especially over the eastern half of the state. Drier, brighter and colder weather will move in for early next week.
Rest of Today: Snow developing from south to north this afternoon. Snow may mix with sleet along the coast. Highs between 25°-37°. Southeast wind becoming northeast and increasing to 10-20 MPH.
Tonight: snow north, snow, mix and freezing rain inland, snow and mix to rain along the coast. Precipitation could be heavy at times. Lows between 21°-31°. North/northeast 15-30 MPH with gusts to 40 MPH possible.
Friday: snow and mix tapers off during the morning then mostly cloudy with scattered snow showers during the afternoon. Highs between 27°-36°. Northwest wind 10-20 MPH.
Saturday: mostly cloudy with scattered afternoon snow showers. Steadier snow possible over the eastern half of the state later in the day and at night. Highs between 27°-34°.
Sunday: mostly cloudy with scattered snow showers. Colder with highs in the upper teens to mid-20s.
Monday: sunny and cold. Highs in the mid-teens to low 20s.
